ITV revealed the damage shortly after Brazil’s controversial 3-1 victory over Croatia. The studio also contained Lee Dixon, Fabio Cannavaro and Patrick Vieira and would have included Roy Keane had he not pulled out of their World Cup coverage.

There were also suggestions that presenter Adrian Chiles was almost hit by a glass bottle as he went out of the studio to try and calm protesters.

The news broke on the same day that a news producer for CNN was left injured after being hit by a stun grenade.
